Hooker Header Inserts
So i know there has been a lot of discussion on these already, but i haven't been able to make up my mind. My car now has just chambered mufflers on it, and its LOUD, too loud. (but sounds awesome) I'm getting sidepipes for it, but i don't want the car to be as loud as it was before, and over the computer i can't really tell how loud the max flo, and sts baffles really are. I don't want it to be quiet by any means, i just want it quieter than it is right now. Opinions would be great. Thanks

That's why I liked the STS baffles . . . you can adjust sound level to some extent. I started with mine capped, but recently drilled the center cap with 1/2" hole and really like the sound. I can drill it out more if I want more sound or I can recap to return to their original level. Here is a video I did, you can't really how loud they are, but it does give you an idea of the sound they make. Sorry, I have not updated the video since I drilled the center cap. Hope this helps:

big question though is what about performance. sidepipes are my next mod so i have been looking into this quite a bit lately.
i dont give a crap about sound. i want performance. i keep reading about how baffles kill hp. which baffle causes the least amount of hp loss. it doesnt matter if it sounds like a gay gorilla yelling whoooooooo as long as it performs.

I went thru the same debate, I decided on Max flows because of the cheaper price tag. I ordered them from a company on ebay and then received an email saying the max flows are backordered until end of august. I was refunded my money and checked with summitracing and jegs and they also were backordered. I didn't have any luck finding them anywhere on the net so I'm still driving around with open 4" pipes

All baffles/inserts rob you of power. The STS are the least restrictive IMO. There have been several CF members who have looked at the flow of the different baffles, so I would recommend doing an advanced search and decide for yourself. I like the auger design myself. Give Jim a call at STS, he is the guy who designed them and I'm sure he can answer your questions . . . real nice guy!!!

If power is your number 1 consideration and you are going to run a muffler than I wouldn't get sidepipes. The sidemount style header is much more restrictive than undercar and the primaries are way longer than ideal, unless you go with Stahl's. Do a nice mandrel bend undercar with Ultraflow or similar mufflers and a poperly sized set of headers.
Now as for sidepipe mufflers, the baffles are the way to go. Tuneable sound and maximum hp. Search, as I have poted my dyno results here many times. In short, an uncapped baffle only lost 12 horsepower on my 614 horse 502.
Tough to beat that. Give Jim at STS a call. He is a straight shooter and a good guy.
